Great to use with our Tankless LPG Gas Portable Instant Water Heaters!

Please note: The only occasions where this Pump is required is where you have longer runs as your pressure will drop over distance due to friction and various other factors. In these circumstances where a longer distance is required to push your water over a greater distance this model is recommended. However our best suited unit is our 6.0 LPM for 90% of all applications.
An example of the use of our 12.5 LPM 40 PSI pump is we had a customer with a problem stating that our unit didn't work when he hooked it up. After fault finding and going through our series of fault finding questions with him we found he was using a 21.0 LPM Pump, however it was only 20 PSI output. He was trying to push water to the Heater unit over a 15 odd metre distance. This was his problem - Plenty of flow rate, not enough pressure to kick in the Piezo ignition on the unit!
